DENTAL GOLD-PELLET HOLDER.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Anplication filed April 28,1906. Serial No. 313,101.

To all whom it may cancer/1 Be it known that I, I'IENRY PORTER DAVIS, acitizen of the United States, residing at Washington, in the District ofColumbia, have invented new and useful Improvements in DentalGold-Pellet Iolders, of which the following is a specification.

My invention relates to new and useful improvements in dental apparatusfor facilitating the operation of filling teeth with gold; and itsparticular object is to provide an instrument specially adapted to holdthe annealed gold in a compact and accessible way, ready to the hand ofthe operator. In

order to carry out this object, I have devised the construction andarrangement of parts illustrated in the accompanying drawings, whereinFigure 1 represents a general side view of my dental gold-pellet holderin its closed position. Fig. 2 represents a top view of the same withthe gold-carrying spindle withdrawn, and Fig. 3 represents said goldcarrying spindle.

In the process of filling decayed teeth with gold it is the usual customto have the gold in small pieces, in a suitable soft or spongy form, andto anneal it shortly before it is used by holding it in a flame for amoment. The bits of gold, usually in pellet or cylindrical form,according to the general practice, are placed in the cavity one at atime and condensed with a plugger or the like. In some cases a holder ormagazine for feedin the gold into the tooth is used. This he der beingheld by the operator in one hand leaves his other hand free to workwith. My improved device is of this character.

Referrin now to the drawings, A is a metallic tube having the narrowopening or slot B along one side, as shown in Fig. 2. At the forward endthe tube is cut away so as to form three spring-like prongs O O O. I mayalso provide this end of the tube with a plugger D, as shown, thoughthis is not really essential. At the rear end the tube terminates in aferrule E.

F is a metallic spindle of approximately the same length as the tube anddesigned to be contained by it. This spindle terminates at the rear endin a convenient handle G. H H, &c., are the pellets or c linders ofgold, which are strung on the spindle F.

The various parts of my invention being constructed and arranged asdescribed, its mode of operation is as follows: W hen it is desired toiill a cavity, I provide one or more spindles loaded with goldcylinders, as shown. I then anneal the gold at one operation and insertthe spindle, with the gold strung on it, in the tube. A slight shake ofthe tube when held upright will now bring one of the cylinders down thespindle till it is held lightly by the retaining-prongs C, whereupon itis readily withdrawn from the tube by the plugger or other instrumentheld in the other hand and placed in the cavity. IV hen this cylinderhad been compressed in the cavity, another one is brought down andtreated in the same way. If a cylinder happens to stick in the tube, itis easily dislodged by running a plugger or the like along the slot B.The lugger D may be used to aid in compressing t 10 gold in the cavity,if desired. The holders can of course be made in various sizes to suitdifferent sizes of gold cylinders. It is possible to use the holderwithout the spindle, the holder in that case being simply loaded withthe gold pellets or cylinders, which are shaken down as needed or pokeddown through the slot. The spindle is a useful feature, however, as itenables the operator to anneal a number of pellets at one time.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A holder for dental-gold pellets consisting ofalongitudinally-slotted tube adapted to receive the gold, and means atthe lower end of the tube for loosely retaining the gold in the tube.

2. A holder for dental-gold pellets consisting of a tube A provided witha longitudinal slot B, open at the forward end, and with spring-likeretaining-prongs C at said forward end, and a spindle F for carrying thegold pellets, adapted to be contained within the tube.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HENRY PORTER DAVIS.
